Title: Improvements in or relating to electric pulse transmission systems
Inventor: LEAKEY DAVID MARTIN
IPC: H04Q11/04
Filed: 1960-09-16
Abstract: 996,381. Semi-conductor circuits; pulse modulation systems; automatic exchange systems. GENERAL ELECTRIC CO. Ltd. Sept. 7, 1961 [Sept. 16, 1960], No. 32001/60. Headings H3T, H4K and H4L. A pulse transmission system comprises a chain of transistor gates, a current being supplied to a first point in the chain so as to maintain one of the transistors non-conductive, further current being supplied to a second point, the directions of the currents being such that one current tends to compensate for loss of pulse amplitude due to the other current. A pulse time division multiplex telephone system is described in which subscribers are arranged in groups of 100 and subdivided into sub-groups of 10. The ten subscribers of one sub-group are connected via their respective modulators 1 to point 9. The points 9 corresponding to the other sub-groups are connected via respective gates 3 to a GO highway 11 the right-hand end of which is fed to a plurality of gates 4 (one per group) and thence via a RETURN highway 14 and gates 5 (one per sub-group) to point 10. A demodulator 2 is provided for each subscriber. Further gates may be included in the transmission path. Diode 33 is normally conductive, maintaining the gating (graded base) transistor 6 and diode 30 non-conductive. When a positive gating pulse at point 29 occurs at the same time as a negative pulse at 35, transistor 6 and diode 30 become conductive, passing a current pulse, the amplitude of which is modulated by diode 24, dependent on the speech voltage fed to transformer 22. Each current pulse fed to point 12 is passed by the appropriate transistors 7, 8 which have been made conductive by gating pulses at 42 and 49. Diode 37 is cut off by each pulse at point 12 so that each pulse is augmented by the current in resistor 36. This compensates for the current taken by resistor 39 which is included to discharge stray and transistor capacitance. Point 12 is clamped by diode 37 at the end of each pulse. Similarly, diode 44 and resistor 43 compensate for the current in resistor 46. The pulses at point 10 appropriate to the required subscriber are routed by diode 55, rendered conductive by negative pulses at 56, to the demodulating transistor 58. The modulation is passed by a low pass filter 61 to the appropriate subscriber. Reference has been directed by the Comptroller to Specification 725,396.

Title: Method of preparing medicines in doses
IPC: A61K9/50
Filed: 1955-11-10
Abstract: A method of making medicinal capsules comprising medicines in predetermined doses dispersed in a carrier comprises preparing a solution or dispersion of the medicine in an aqueous solution of a swellable colloid, e.g., gelatin, agar-agar, gum acacia, pectin, starch, tragacanth or casein, warming the solution, e.g., to 50 DEG C. and adding dropwise to a water immiscible liquid of lower density than the solution or dispersion and which is contained in a tall cylinder, the top part of which is maintained at a temperature akin to the solution and the bottom of which is maintained at a temperature at which the colloidal carrier is solid.  The droplets, as they descend the cylinder congeal to form solid "pearls" containing an amount of medicine determined by the size of each droplet.  Specification 708,160 [Group VI] is referred to.ALSO:A method of preparing medicines in doses dispersed in a carrier, comprises preparing a solution or dispersion of the medicine in an aqueous solution of a swellable colloid, e.g. gelatin, agar-agar, gum acacia, pectin, starch, tragacanth or casein.  This solution or dispersion is then added dropwise, after warming, e.g. to 50 DEG  C., to a water-immiscible liquid of lower density than the solution or dispersion and which is also a non-solvent for the medicine, e.g. paraffin oil, or an animal or vegetable oil.  This liquid is contained in a tall vertical vessel, the top part of which is maintained at a temperature similar to the colloidal dispersion or solution, e.g. 50 DEG  C., and the bottom of which is at a lower temperature, e.g. 20 DEG  C.  On descending the vessel the drops congeal forming "pearls," containing the medicine dispersed in the carrier.  The "pearls" are incompletely washed with benzene to remove part of the adhering oil, dried and washed free of all oil.  Water may be removed with a water-miscible solvent, e.g. acetone, methanol, ethanol, propanol or dioxan.  The colloidal solution may also contain a plasticizing agent, e.g. glucose, sorbitol, glycol or hevey.  If the medicine has been incorporated in an oil form and clear "pearls" are required, resin may be added to the oil phase of the dispersion to equalize the refractive indices of the two phases.  The pH of the colloidal solution or dispersion is adjusted closely to the isoelectric point of the swellable colloid used, before pouring dropwise into the congealing medium.  If a cellulose derivative, e.g. carboxymethyl cellulose, is used as the carrier, the coagulating vessel may contain an aqueous solution of an acid, or an organic solvent.  The example given is for a multivitamin preparation. Specification 708,160 is referred to.
Patent GB-263199-A (GB)
Title: An improved process for the production of active silica gels with fine capillary pores
IPC: C01B33/158
Filed: 1926-12-20
Abstract: 263,199. I. G. Farbenindustrie Akt.- Ges. Dec. 19, 1925, [Convention date]. Right to Patent relinquished. Silica.-Silica gel having fine pores is obtained by treating a silica jelly before or during drying and in any case before contraction is complete, with an electrolyte such as to impart to it a hydrogen-ion concentration pH between 2 and 6.5. The jelly may be prepared in any suitable way, preferably by way of a neutral or nearly neutral or slightly acid sol, and the electrolyte may be added in the form of suitably adjusted washing-water. The materials mentioned as initial materials for the production of the gel are soluble or insoluble silicates, zeolites, slags, silicon tetrachloride, or silicon fluoride, and the decomposing agents may be acids or solutions of metallic salts, in which case the gels may contain metallic oxides or hydroxides. It is preferred to obtain the jelly from a sol of a neutral, weakly alkaline, or slightly acid reaction, and containing at least 50 and preferably 120 or more grams, silica per litre, and salts produced in the reaction are preferably removed by washing. If the jelly is strongly acid, the washing may he effected first with alkaline water, then with distilled water, and then with water having the same or a lower hydrogen-ion concentration than the jelly possesses. The drying temperature may be high or low but is preferably over 120‹ C. and may be conducted in stages, the first stage being below 400‹ C., for instance 75-200‹ C. The drying may be effected in air or in vacuo, or in contact with hot combustion gases in tunnel or rotary ovens. The jelly may be more or less completely purified, with or without pressure, before or after drying or pre-drying, after which a further purification may be effected, preferably after a treatment with water vapour. The drying may be preceded by moulding the completely or partially purified jelly or precipitate, preferably while containing about 90 per cent of water. In an example, the jelly is produced from sodium silicate, sulphuric acid, and ice, the sol being coagulated by heating and stirring. The jelly is broken up and washed to remove nearly all the salts, until it gives a yellow or bluish-green coloration with bromo-cresol green, or a yellow coloration with cresol red. Preferably the washing-water, containing hydrochloric acid, gives a bluish-green coloration with bromo-cresol green, when its pH is about 3. The jelly is dried in hot air at 150-200‹ C., followed if necessary by a higher temperature. Specifications 255,863 and 255,864 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) gives the limits of pH as 1 to 6.5. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in loading apparatus for concrete or other materials
IPC: B28C7/08
Filed: 1923-12-22
Abstract: 218,202. Fowler & Co. (Leeds), Ltd., J., and Wilcock, C. M. Dec. 22, 1923. Feeding-devices for granular and like materials.-Relates to power-operated loading-apparatus comprising a pivoted shoot or hopper which is swung by power from an horizontal position to an inclined position to discharge the concrete or other materials contained therein. The winding-gear for elevating the shoot or hopper to discharge position comprises a controlled clutch and means for temporarily releasing the clutch when the hopper is in discharge position and for permitting of the re-engagement of the clutch when the hopper has receded for a short distance from the discharge position, for the purpose of giving a shaking movement to the hopper during the discharge. The hopper A is pivoted on a rod B, and the ends of a wire rope D passing through a tubular transverse member C held by lugs C<1> on the hopper are attached to two winding-drums E, E<1> on a shaft F carried by bearings on a fixed frame G. The shaft F carries a drum H of larger diameter than, and conveniently in one with, the drum E', and a rope J is attached at one end to the drum H and at the other end to a drum K forming part of one member L of a clutch L, L<1>, the other member L' being keyed to the power shaft M. The member L is movable along the shaft M under control of the striking-gear lever O operated by a handle N. The lever O is pivoted at U and is moved by the cranked end P of a rocking-shaft Q which is mounted in bearings R and carries an adjustable arm S against which a stud T on the hopper strikes when the hopper has been elevated to discharge position. When the stud T engages the arm S, the cranked end P gives an outward jerk to the lever O against the pressure of the operator's hand on the handle N, thereby permitting of the temporary disengagement of the clutch L, L<1> and allowing the hopper to fall back slightly under the reaction of a spring plunger V before the continued pressure of the operator's hand can restore the clutch to engagement, whereupon the stud T will again contact with the arm S. This movement is repeated so long as the operator presses sufficiently upon the handle N and until the desired quantity of material has been discharged from the hopper A. On releasing the pressure on the handle N, the ropes J, D will unwind and allow the hopper to fall back to the loading position.
